Question

А) 6b-(2+3b)= б)-3(x+5)+6(x-2)= в)1/6x+2 1/3=5/6= г)y:3 1/3=1 1/5:1/2

Answer 1

А) 6b-(2+3b) =6b-2-3b=3b-2
б) -3(x+5) +6(x-2) =-3x-15+6x-12=3x-3
в) 1/6x+2 1/3=5/6
1/6x+7/3=5/6
1/6x=5/6-7/3
1/6x=-9/6
x = -9/6: 1/6
x = -9
г) y: 3 1/3=1 1/5: 1/2
y: 10/3=6/5: 1/2 = 6/5 × 2/1
y: 10/3 = 12/5
y = 12/5 × 10/3
y = 8

Answer 2

а) 2/3

б) 9

в) -1/9

г) 14 2/3
